Hi @Ify47,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your screen brightness is stuck at maximum on your HP Omen 15 (model en0023dx) after a motherboard replacement, and you've already tried reinstalling Windows, downgrading the BIOS, and reinstalling drivers, here are a few additional steps you can take to troubleshoot and potentially resolve the issue:

1. Check Power Settings:

Ensure that your power settings allow for brightness adjustment.

• Right-click on the battery icon in the taskbar and select "Power Options."
• Click on "Change plan settings" next to your current power plan.
• Click on "Change advanced power settings."
• Expand the "Display" section and then the "Enable adaptive brightness" section. Make sure adaptive brightness is turned off for both "On battery" and "Plugged in."

2. Update or Rollback Display Driver:

• Open Device Manager (right-click Start button and select "Device Manager").
• Expand the "Display adapters" section.
• Right-click on your graphics card and select "Update driver." Choose to search automatically for updated driver software.
• If updating doesn't work, try rolling back the driver: Right-click on the graphics card, select "Properties," go to the "Driver" tab, and click "Roll Back Driver" if the option is available.

3. Check the Intel Graphics Command Center or NVIDIA Control Panel:

Depending on your GPU, the brightness settings might be controlled by the graphics card software.

• For Intel: Open the Intel Graphics Command Center, navigate to "System," then "Power," and adjust the display power settings.
• For NVIDIA: Open the NVIDIA Control Panel, go to "Display," and look for any settings related to brightness or color.

4. BIOS Settings:

Sometimes, the BIOS settings can affect display brightness.

• Restart your laptop and enter the BIOS setup (usually by pressing F10, F2, or Del during boot).
• Look for any settings related to the display or brightness and ensure they are properly configured.

5. Check for Windows Updates:

Make sure your Windows 11 installation is fully up-to-date.

• Go to Settings > Update & Security > Windows Update, and check for updates.

6. Reset BIOS to Default Settings:

If you've downgraded the BIOS, resetting it to the default settings might help.

• Enter the BIOS setup during boot.
• Look for an option to reset to default settings, often found under an "Exit" or "Advanced" tab.

7. Use HP Support Assistant:

• Download and install the HP Support Assistant if you haven't already.
• Use it to check for any system updates or driver updates that might be specifically tailored for your HP Omen model.

8. Hardware Diagnostics:  HP PCs - Testing for hardware failures 

Run HP's hardware diagnostics to check if there are any underlying hardware issues.

• Restart the laptop and press F2 repeatedly until the HP PC Hardware Diagnostics UEFI menu opens.
• Run the diagnostics tests for the display and other components.
